[0028] like Figure 1-2 As shown, a flap-type fireproof rolling shutter 3 includes a door frame 1, a frame 2, a rolling shutter 3, a driving device 4, a controller 5, and a sprinkler pipe 6;

[0029] A driving device 4 is provided on one side of the top of the door frame 1, and a spray pipe 6 is provided on the other side. The spray pipe 6 is provided parallel to the top of the door frame 1; the distance between the driving device 4 and the top of the door frame 1 is not less than the length of the frame 2;

[0030] The frame 2 is hinged at the top inner side of the door frame 1 , a rolling curtain 3 is arranged inside the frame 2 , and the rolling curtain 3 is flatly clamped inside the frame 2 ; the driving device 4 is connected to the bottom end of the frame 2 through a steel wire rope 404 .

[0031] Specifically, the driving device 4 includes a driving motor 401 and a transmission shaft 402. The driving motor 401 is a forward and reverse motor. The driving motor 401 is connected to the transmission shaft 402 through a transmission chain. Rollers 403 are provided at both ends of the transmission shaft 402. The transmission shaft 402 is arranged parallel to the top of the door frame 1.

[0032] Specifically, fixing rings 201 are provided at both corners of the bottom end of the frame 2 .

[0033] Specifically, a steel wire rope 404 is rolled up on the roller 403 , one end of the steel wire rope 404 is fixedly connected to the roller 403 , and the other end of the steel wire rope 404 is fixedly connected to the fixing ring 201 at the bottom end of the frame 2 .

[0034] Specifically, the spray pipe 6 is provided with a plurality of spray holes at equal intervals toward one side of the top end of the door frame 1 .

[0035] Specifically, a controller 5 is provided on the door frame 1, and the controller 5 is connected to the drive motor 401 in the drive device 4 through a cable.

[0036] Specifically, the controller 5 is sampled and connected to the switch of the spray pipe 6.

[0037] Specifically, a clamping groove 101 is provided on the inner edge of the door frame 1, and it can be clamped and connected to the frame 2 through the clamping groove 101.

[0038] Specifically, a weight block 202 is provided inside the bottom end of the frame 2.

[0039] In normal times, as Figure 3 shown, the frame 2 carrying the rolling shutter 3 inside it is placed flat on the end face of the top wall 7 of the channel. The spray pipe 6 and the drive device 4 are respectively fixed on the wall surfaces of the top wall 7 on both sides of the door frame 1. Among them, the top end of the frame 2 is hinged to the inner top end of the door frame 1, and the other end is tied to the transmission shaft 402 through a steel wire rope 404. The transmission shaft 402 is braked by the drive motor 401 to prevent it from rotating. When the rolling shutter door needs to be closed, as Figure 4 shown, the drive motor 401 can be started through the controller 5. The drive motor 401 drives the transmission shaft 402 to rotate. The rollers 403 at both ends of the transmission shaft 402 perform the operation of releasing the steel wire rope 404 wound thereon. The bottom end of the frame 2 makes a circular motion around the top end of the door frame 1 as the steel wire rope 404 is lowered until the frame 2 is clamped into the clamping groove 101 of the door frame 1 (as Figure 5 shown). If the fire lasts for a long time, the spray pipe 6 can be started through the controller 5 according to the actual situation to spray water on the top end of the rolling shutter 3, so as to cool the rolling shutter 3 for protection. When the rolling shutter door is opened, the drive motor 401 is started through the controller 5 to perform a reverse movement. The drive motor 401 drives the transmission shaft 402, and the transmission shaft 402 drives the rollers 403 to wind up the steel wire rope 404. The bottom end of the frame 2 is lifted and retracted until the frame 2 is parallel to the end face of the top wall 7, completing the retraction operation.

[0040] Among them, the weight block 202 is used to increase the weight of the bottom end of the frame 2. The total weight of the frame 2, the rolling shutter 3 and the weight block 202 can ensure that the frame 2 is finally successfully clamped into the clamping groove 101 of the door frame 1. Secondly, the spray pipe 6 is used to cool the rolling shutter 3 inside the frame 2 and increase the fire resistance duration of the rolling shutter 3.
